* |
|
* The sample values can have any dimensionality and derived classes may |

/** |
|
* |
|
* A group of objects that receives a shared animation state. |
|
* |
|
* Usage: |
|
* |
|
* - Add objects you would otherwise pass as 'root' to the |
|
* constructor or the .clipAction method of AnimationMixer. |
|
* |
|
* - Instead pass this object as 'root'. |
|
* |
|
* - You can also add and remove objects later when the mixer |
|
* is running. |
|
* |
|
* Note: |
|
* |
|
* Objects of this class appear as one object to the mixer, |
|
* so cache control of the individual objects must be done |
|
* on the group. |
|
* |
|
* Limitation: |
|
* |
|
* - The animated properties must be compatible among the |
|
* all objects in the group. |
|
* |
|
* - A single property can either be controlled through a |
|
* target group or directly, but not both. |
